DERAILING DEVICE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed September 26, 1913. Serial N 0. 791,957.

To all whom it may concern:

Be it known that 1, JOHN A. BODKIN, a citizen of the United States, residing at New York, county of New York, State of New York, have invented a certain new and useful Improvement in Del-ailing Devices, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object to produce a cheap and simple derailing device.

A further object of my invention is to produce a derailing device which may be applied to a rail without requiring the drilling of holes in the rail.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, where- 1n Figure 1 is a plan View of the meeting ends of two rails having my improved device applied thereto; Fig. 2 is a section on line 22 of Fig. l; and Fig. 3 is a plan view of the bolt member of the derailer.

In accordance with my invention I construct the derailing device of two members, a casting, 1, adapted, when in derailing position, to rest upon a rail and provided with the usual groove, 2, for guiding a wheel flange from one side of the rail across the top to the other side; and a securing or holding member, 3. The securing or holding member is made in the form of a U-bolt having its arms, 4, spaced apart a distance corresponding to the spacing between the two center bolt holes of standard splice bars, the diameter and length of the members 4. being such as to adapt these members to take the place of the two center bolts of an ordinary rail joint. The arms of the U- shaped bolt are preferably provided near theirconnected ends with shoulders or enlargements to serve as engaging means with the adjacent splice bar and permit the yoke member to be spaced apart from the splice bar. This may conveniently be accomplished by making the yoke and the adjacent portions of the arms somewhat larger in diameter than the remainder of the arms, as illustrated. The derailing block is provided with a lateral projection, 5, whose lower end, 6, is curved into the form of a hook which is adapted to be passed between the yoke of the holding member and the adjacent splice bar and form with the yoke a hinge connecting the bolt and the block together. If desired, the member 5 may be provided with a lug or car, 7, by means of which the block may be connected to a switch stand so as to be capable of being thrown into and out of working position from the stand.

My improved device is intended to be applied to the rails at a joint, but it will of course be understood that, if desired, the de vice may be applied at any point along a rail if the proper holes are drilled. In applying the device, the two central bolts of a joint between two rails, such as indicated at 8 and 9, are removed, the U-shaped bolt is slipped into the joint in place of the bolts which have been removed, and suitable nuts, 10, are screwed upon the ends of the arms of the U-bolt, leaving the joint in the same condition as it was before the two center bolts were removed. In the preferred arrangement, the hook 6 on the block is so shaped that it cannot be removed from the U-bolt while the latter is in position as part of the rail joint, in this case, it will of course be necessary first to hook the block upon the U-bolt before the latter is placed in the joint.

It will thus be seen that I have provided a simple and novel derailing device comprising only two members, and one which may be securely connected to a railway rail without drilling holes in the rail.

lVhile I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described, but intend to cover all forms and arrangements which fall within the terms of my invention constituting the appended claims.

I claim:

1. A device of the character described, comprising a Ubolt adapted to replace the two middle bolts of a rail joint, and a derailing block hinged to the bolt.

2. A device of the character described, comprising a U-bolt adapted to replace the two middle bolts of a rail joint, and a derailing block hinged to the yoke of the bolt.

A device of the character described,

comprising a U-bolt and a derailing block hinged on the yoke of the bolt.

(3. In combination, two meeting rail ends, splice bars connecting the ail ends, a derailing block, and a hinge for said block including two boltlike parts extending through two of the bolt holes in the splice bars and the rail ends.

7. In combination, two meeting rail ends, splice bars for connecting said rail ends together, a block, and a hinge support for said block adapted to support the same so as to permit it to be swung from a position above the rail ends to a position at one side of the rail, said support including two boltlike members extending through the rail ends and the splice bars and serving to clamp the rail ends between the splice bars.

In testimony whereof, I sign this specification in the presence of two witnesses.
